MOTOR FUEL PRODUCTION METHOD AND INSTALLATION Russian patent published in 2018 - IPC C10L1/00 C10G35/04 C10L10/10 C10G7/02 

FIELD: technological processes.

SUBSTANCE: invention describes the motor fuel production method, characterized in that the hydrocarbon condensate is in series heated in the first and second recuperative heat exchangers and the preheater and for the fractions separation supplied to the distillation column bottom, withdrawn from the distillation column middle portion diesel fraction enters the stripping column heated by the heat of the fuel oil fraction withdrawn from the distillation column bottom, and after cooling in the second recuperative heat exchanger and the second cooler, the diesel fraction is supplied to the storage, at that, the fuel oil fraction from the distillation column heats the stripping column still, then gives off heat in the first recuperative heat exchanger and in the first cooler, after which it is either returned to the condensate flow to the storage or used as the liquid fuel, withdrawn from the distillation column top gasoline fraction vapors are condensed in the third cooler, the condensed gasoline fraction is supplied to the reflux tank, and then partially to the distillation column top for irrigation, most of the gasoline fraction (naphtha) is returned to the condensate stream, and the rest of the condensed gasoline fraction is supplied through the third recuperative heat exchanger to the high octane gasoline production unit, at that, to the third recuperative heat exchanger input methanol and / or water containing liquid and / or vapor medium is additionally supplied, the gasoline fraction and said medium heated mixture enters one of the catalytic reactors, catalyst from this catalytic reactor enters to the stabilization column heating, then enters to the third recuperative heat exchanger heating and after passing through the fourth refrigerator enters the separator, from where the gas phase enters the fuel network, water enters to the draining, and through the coalescer the liquid hydrocarbon phase flows through the fifth recuperative heat exchanger to the stabilization column middle part for the light fractions separation, which from the stabilization column top through the fifth refrigerator enter the irrigation tank, from which the formed liquefied propane-butane fraction partially comes into the stabilization column for irrigation, and partly is into the fuel network, after cooling in the fifth recuperative heat exchanger and the sixth cooler, from the stabilization column bottom the stable gasoline fraction enters the warehouse, at that, preheated in the fourth recuperative heat exchanger the nitrogen-air mixture enters the second catalytic reactor for the catalyst reduction. Motor fuel production unit is also disclosed.

EFFECT: improving the target products quality, resulting in the cleaner target products production.
